Communication protocol is an automatic fire alarm system completes the information transfer, confirmation and response must follow the rules "of", the system only rely on perfection of a reasonable standard for system components and even broader information exchange in order to complete the expansion and optimization system.
At present, "to a variety of bus systems" to the mainstream of automatic fire alarm system is universal and promotion, but there is no "bus-automatic fire alarm system," protocol standard for technical design come from different sources (introduction, cooperation, development and imitation), its communication protocol wuza diverse raises many questions.1.1.1 product development and manufacturing of benign development difficult technical resources to take full advantage of
(1) the research and development and manufacturing enterprises in the product development application behavior closed-door self-locking, technology, technology contents wuza of large, difficult to circumvent weaknesses, reasonable and orderly, much less in sync with the advanced technology and international standards.
The system of sealing causing different manufacturers of products are not interchangeable, system extensions, restricted the automatic fire alarm industry development.(2) duplicate development, information resources cannot be shared, technology and resource duplication costs, product development, high costs, long life cycle, it is difficult to seize the market opportunities and market stability.
(3) communication protocol standardization, product technical performance is good or bad the lack of definition and identification of uniform standards, it is difficult to achieve in the strict sense for the survival of the fittest, not only hinder the application of new technology and development, also in disguise as the enterprise of unfair competition.
1.1.2 system maintenance lack of standards, sustainable technology support
(1) due to the lack of standardized, unified communication standards, different fire auto-alarm device is not interchangeable, once the system is in need of repair, replace, clean, user you may damage the device without maintenance replacement, and forced to comprehensive selection of new and waste heat exchanger or other enterprise products, or because the necessary technical support and allow building failure automatic fire system crashes, the former waste of national property, the latter forming a fire hazard.
(2) as the communication protocol, allowing users once you have selected the one product will never be affected by the enterprise.
(3) as the communication protocol is not uniform, will give a variety of automatic fire alarm products into the standardization of wide area network management resulting in barriers to the relevant State departments or on the Internet on any of the automatic fire alarm health to carry out the necessary supervision and inspection and unified command.
(4) with the economic development of a building or a factory at the same time run two or more fire alarm host of more and more.
How to manage these different manufacturers, different eras, different types and separate fire alarm system is a headache.1.1.3 user operations using the difficulties
Due to a fire alarm devices and dominate the market not a absolute strength products, but also because of the standard specifications for manufacturers leave too much room for play, so the fire alarm device hosts like PC like a thousand people, but a thousand thousand faces, plus the product imported, the user interface more rendering "United Nations" effect; the user interface on the device itself is not friendly, and the daily use and operations personnel are not good professional technical quality and foreign language skills, coupled with frequent changes of personnel and management system, so a large part of the fire-fighting facilities run blurry, it cannot be said to bad termsof, users use the enthusiasm is not high.
1.2 automatic fire alarm system of false positives, false negatives problems users
